<a name="GNotification.description"></a><h2>Description</h2>
<p><a class="link" href="GNotification.html" title="GNotification"><span class="type">GNotification</span></a> is a mechanism for creating a notification to be shown
to the user -- typically as a pop-up notification presented by the
desktop environment shell.</p>
<p>The key difference between <a class="link" href="GNotification.html" title="GNotification"><span class="type">GNotification</span></a> and other similar APIs is
that, if supported by the desktop environment, notifications sent
with <a class="link" href="GNotification.html" title="GNotification"><span class="type">GNotification</span></a> will persist after the application has exited,
and even across system reboots.</p>
<p>Since the user may click on a notification while the application is
not running, applications using <a class="link" href="GNotification.html" title="GNotification"><span class="type">GNotification</span></a> should be able to be
started as a D-Bus service, using <a class="link" href="GApplication.html" title="GApplication"><span class="type">GApplication</span></a>.</p>
<p>User interaction with a notification (either the default action, or
buttons) must be associated with actions on the application (ie:
"app." actions).  It is not possible to route user interaction
through the notification itself, because the object will not exist if
the application is autostarted as a result of a notification being
clicked.</p>
<p>A notification can be sent with <a class="link" href="GApplication.html#g-application-send-notification" title="g_application_send_notification ()"><code class="function">g_application_send_notification()</code></a>.</p>
